Is Corn Low FODMAP and Suitable for Tummy Troubles?


If you’re a parent wondering whether corn is suitable for your child during the low FODMAP diet trial, you’ve come to the right place! 

Let’s explore the intricate world of FODMAPs, decode corn’s composition, and determine its suitability for those dealing with digestive issues related to irritable bowel syndrome (IBS). 

This article aims to provide you with the knowledge needed to make informed decisions about incorporating corn into a low FODMAP diet. Let’s get started!

Is corn low FODMAP?

When embarking on the low FODMAP diet trial, many parents question the FODMAP status of corn. 

The good news is that corn is generally considered low in FODMAPs. 

This means it can be a suitable vegetable for children and adults dealing with IBS-related constipation or diarrhoea. 

However, it’s important to note that there are a few exceptions to keep in mind. 

Corn does contain small amounts of fructans, which fall under the category of FODMAP foods. 

As FODMAPs can accumulate with larger portion sizes, it’s crucial to be mindful of this during the diet trial. 

Remember, controlling portion sizes play a vital role in managing your child’s overall FODMAP intake. 

In the following sections, we’ll delve deeper into the FODMAP content of corn.

Serving size and FODMAPs why it’s so important

When it comes to managing your child’s digestive issues, one aspect often overlooked is serving size and how much to serve your child at mealtimes. 

Understanding the significance of portion control is essential for your child’s FODMAP journey. 

Let’s take corn thins as an example. 

While one corn thin is considered low in FODMAPs, exceeding the recommended portion can push the fructan limit, making them high in FODMAPs according to Monash ratings. 

By paying attention to serving sizes, you can ensure your child stays within the recommended FODMAP limits during the low FODMAP diet trial. 

Remember, small adjustments in portion sizes can make a big difference in your child’s symptoms.


The FODMAP in Corn

To fully comprehend how corn affects digestive health, it’s crucial to understand its FODMAP content. 

Fresh corn contains sorbitol, which is a type of FODMAP that may cause discomfort for some children. 

However, when it comes to corn, it’s the fructans that demand attention. 

Larger portion sizes of corn can increase the fructan levels, turning it into a higher FODMAP food. 

¾ cob of corn or 63 grams contains a moderate amount of sorbitol.

It’s important to be aware of this when incorporating corn into your child’s diet.


Fresh and tinned corn: Understanding FODMAP Levels

Although corn is generally considered an example of low fodmap food, fresh corn, particularly in larger quantities, can become a high FODMAP food due to its sorbitol and fructan content. 

On the other hand, the canning process generally reduces FODMAP levels in food, and sweetcorn is no exception. 

Canned baby corn

The good news is that canned or tinned baby corn is also a low FODMAP corn.

Canned baby corn is a low FODMAP food, providing an ibs-friendly low fodmap snack option during the elimination phase. 

It can also be easily incorporated into low-FODMAP dinner recipes.

Canned corn kernels

Similarly, canned sweet corn kernels are generally low in FODMAPs, allowing children to enjoy their favourite vegetables while adhering to the low FODMAP diet. 

However, it’s crucial to be mindful of portion sizes.

If children eat large quantities of canned corn kernels, this increases their intake of fructans which can potentially trigger diarrhoea or tummy pain in children.

To strike a healthy pain-free balance, offer your child canned corn kernels in moderate portion sizes.

This way your child won’t feel deprived and will be able to enjoy the delicious flavours of sweetcorn without compromising their FODMAP management.

How much frozen corn is low FODMAP?

When it comes to determining how much frozen corn is low FODMAP, a helpful approach is to treat frozen corn products just like their natural or raw counterparts. 

This means considering the FODMAP content of fresh corn and applying the same guidelines to frozen corn. 

For instance, if a small portion of fresh corn is considered low in FODMAPs, you can use that as a reference for determining a suitable serving size for frozen corn. 

By treating frozen corn in this way, you can ensure that you’re making informed choices and managing your child’s FODMAP intake effectively during their low FODMAP diet trial.

Canned creamed corn

For young children, a small amount of canned creamed corn is considered a low FODMAP food.

They can enjoy it freely without worry. However, as children grow older and for adults, it’s important to be mindful of serving sizes. 

Larger portions of canned creamed corn can be a significant source of fructans, which may trigger symptoms like tummy pain and changes in stool patterns for those sensitive to fructans. 

Controlling portion sizes and encouraging moderate consumption of canned creamed corn is key.

Paying attention to portion sizes is key (versus complete avoidance of corn products).

This way, your child can enjoy variety in their diet whilst effectively managing their FODMAP intake.


Other corn products

Let’s discuss other corn-based products, such as cornflakes and corn crisps. 

Corn flakes

A small serving of cornflakes falls within the low FODMAP range, making it suitable for most children during the low FODMAP diet trial. 

However, it’s important to note that older children may consume larger portion sizes, exceeding the recommended limit.

This can easily make cornflakes unsuitable for the low FODMAP trial. 

Some brands have analyzed their cornflakes for their unique FODMAP levels, providing valuable information on safe quantities for children and adults. 

Do look out for these certified products which can be a useful addition to your child’s diet.

Corn crisps

As for corn crisps, a small bag is typically low in FODMAPs, offering a satisfying and safe snack option for kids. 

However, it’s essential to read the nutrition labels to ensure there are no other added sources of FODMAPs, as certain flavours or seasonings may contain hidden high FODMAP ingredients. 

By selecting corn crisps without additional FODMAPs, you and your child can indulge in a tasty treat worry-free.

Incorporating corn into a low FODMAP diet requires understanding its FODMAP content and practising portion control. 

By making informed choices about corn and its various forms, you can strike a balance between your child’s enjoyment of this beloved grain and their digestive well-being. 

Remember to consult with a healthcare professional or registered dietitian for personalized guidance tailored to your child’s specific needs. Happy shopping and happy tummies!


Corn flour

Corn flour is a useful gluten free ingredient for preparing sauces and thickening dishes. 

The good news is that corn flour is considered low in FODMAPs.

It’s a versatile option to incorporate into your child’s low FODMAP diet. 

You can use corn flour freely without any restriction, for its thickening properties without worrying about triggering FODMAP-related symptoms. 

So go ahead and confidently use corn flour for thickening sauces or in baking.

It’s a safe and suitable choice for managing your child’s FODMAP intake.


Cornmeal is generally considered a low FODMAP food.

But the addition of other ingredients such as wheat flour or high FODMAP sweeteners can affect its overall FODMAP status. 

If you’re purchasing cornbread in the UK, it’s important to carefully read the ingredient labels or look for certified low FODMAP options. 

Alternatively, you can also try making your own cornbread using low FODMAP ingredients to ensure it meets your child’s dietary needs. 


Sweeteners and their FODMAP grading

Is corn syrup low fodmap?

Corn syrup is made by extracting the sugars from cornstarch, and during this process, some of the FODMAPs are removed. 

Corn syrup is considered fodmap friendly as it mainly contains glucose.

It may also be listed as glucose syrup or dextrose.

Is high fructose corn syrup low fodmap?

Monash explains this information in good detail.

In high fructose corn syrup, the corn syrup contains more than 50% of excess fructose.

The short answer is that high fructose corn syrup is not low FODMAP.

In the UK and Europe, high fructose corn syrups or corn syrups containing more than 50% fructose is listed as fructose-glucose syrup. 

These syrups are the same as high fructose corn syrup and are high in FODMAP.

Some examples of foods containing high fructose corn syrup include McVities hobnobs, Jaffa cakes and Mr Kipling Bakewell Slices.


As you can see, corn can be a suitable option for children on a low FODMAP diet.

You just need to be mindful of portion sizes and potential FODMAP content. 

While corn is generally low in FODMAPs, larger portions or certain corn-based products may contain higher levels of fructans, which can trigger symptoms in children with IBS.
